Refactor `ModalDialog` unit tests to use `shallowMount` consistently. Previously, tests sometimes failed due to the `UseSvgLoader` hook attempting icon loads during component teardown, which occasionally led led to errors when the `window` object became unavailable. By switching to `shallowMount`, tests no longer deeply render child components, mitigating the risk of such errors and aligning with unit testing best practices. Additionally, this commit sets a default value for the `modelValue` prop in test setups to address Vue warnings about missing required props, further stabilizing the test environment.
